Section snippets
Patients
One hundred eleven patients were included in a three-center, prospective, crossover study comparing H-PSG with TPSG performed in two respiratory medicine units (Hôpital Tenon, Paris; Hôpital A. Mignot, Versailles) and telemonitored by the Hôpital Saint Antoine sleep laboratory in Paris. Patient inclusion criteria were clinical suspicion of OSAS (snoring plus excessive daytime sleepiness plus apneas described by the patient's relatives), and physical capacity to comply with the two diagnostic
Results
Ninety-nine of the 111 patients included actually participated in the study; 55 patients were enrolled in Hôpital Tenon, and 56 patients were enrolled in Hôpital de Versailles. The male overrepresentation (83%), the mean age (52 years), and the relative obesity (mean body mass index [BMI], 27.5 kg/m2) corresponded to the anthropometric profile usually observed in OSAS patients. Six of the remaining 12 patients refused the recording at the last moment (4 patients refused both T-PSG and H-PSG,
Discussion
This study demonstrates that T-PSG is clearly superior to H-PSG in terms of recording legibility, and tends to be preferred by the patients. The site of recording, whether at home or in the hospital, has no overall influence on TST, sleep composition, and frequency of abnormal respiratory events. With an AHI cutoff value of 10/h for the diagnosis of OSAS, H-PSG and T-PSG findings were concordant in 58 of 65 patients.
Our results in terms of ambulatory polysomnography failures are very similar to

2021, Sleep Medicine ClinicsCitation Excerpt :However, evidence on the efficacy of telemonitored (P)SG is weak. Gagnadoux and colleagues23 reported that PSG performed in a local hospital and telemonitored by a sleep laboratory was clearly superior to unattended home PSG. Kristo and colleagues24 proposed a telemedicine protocol for the online transfer of PSGs from a remote site to a centralized sleep laboratory, that had practitioners for diagnosis, which provided a cost-saving approach for the diagnosis of OSA.

2015, Sleep MedicineCitation Excerpt :H-PSG set-up can be performed both at home (H-PSG) and in the sleep laboratory (LH-PSG). Results from previous studies show a relatively high failure rate of H-PSG, which suggests that this might be related to hook-up within the hospital where patients have to travel with a fitted PSG [7,8], which can lead to data loss. This hypothesis is also supported by observations from other studies which used the set-up at home, and it reported a similar quality of recordings between H-PSG and attended in-laboratory PSG [9].
